摘　　要：为探究物流仓储场地土壤中重金属污染特征及对人群健康的潜在影响,以北方某市郊区物流仓储退役场地为研究区域,检测分析4个样地土壤的污染水平,并进一步评价污染物的累积程度及环境健康风险。结果表明,4个样地土壤中重金属浓度水平均未超过GB 36600—2018《土壤环境质量建设用地土壤污染风险管控标准(试行)》中第二类建设用地标准值,但部分重金属元素特别是Pb和Hg的浓度高于区域背景值,且4个样地的重金属综合累积指数均超过1,说明物流仓储活动对该地区的土壤环境造成了一定影响。环境健康风险评价显示,4个样地的总致癌风险均高于1×10^(−6),属于不可接受水平,需要进一步关注污染的潜在人群健康损害。研究结果可为物流仓储场地土壤污染防控以及潜在风险识别和管控提供科学数据。In order to explore the characteristics of heavy metal pollution in the soil of logistics storage sites and their potential impacts on human health,the decommissioning site of logistics storage in the suburbs of a northern city was taken as the research area,the soil pollution levels of four sample sites were detected and analyzed,and the accumulation degree of pollutants and environmental health risks were further evaluated.The results showed that the concentration of heavy metals in the soil of the four sample plots did not exceed the standard value of the second type of construction land of Soil Pollution Risk Control Standard for Soil Environmental Quality Construction Land(Trial)(GB 36600-2018).However,the concentrations of some heavy metals,especially Pb and Hg,were higher than the regional background value.Furthermore,the comprehensive accumulation index of heavy metals in the four sample plots was more than 1,indicating that logistics and warehousing activities had a certain impact on the soil environment in the region.Environmental health risk assessment showed that the total carcinogenic risk of the four plots was higher than 1×10^(−6),which was an unacceptable level,and further attention should be paid to the potential human health damage caused by pollution.The results could provide important scientific data for the prevention and control of soil pollution in logistics warehousing sites,as well as the identification and management of potential risks.
